This is the start of the flyover tests. It's coming along, but its not complete yet.

Notes:
1.) The unit tests focus on some of the helper functions right now.
2.) Midpoint of two points is tested
3.) Distance between two points is tested

Things to come:
1.) Flyover tests, will be pass fail situation with different DEM's loaded
2.) DEM boundaries (this sounded like it was breaking (when paths are being constructed)
